RESUMO
Some living kidney donors incur economic consequences as a result of donation; however, these costs are poorly quantified. We developed a framework to comprehensively assess economic consequences from the donor perspective including out-of-pocket cost, lost wages and home productivity loss. We prospectively enrolled 100 living kidney donors from seven Canadian centers between 2004 and 2008 and collected and valued economic consequences ($CAD 2008) at 3 months and 1 year after donation. Almost all (96%) donors experienced economic consequences, with 94% reporting travel costs and 47% reporting lost pay. The average and median costs of lost pay were $2144 (SD 4167) and $0 (25th-75th percentile 0, 2794), respectively. For other expenses (travel, accommodation, medication and medical), mean and median costs were $1780 (SD 2504) and $821 (25th-75th percentile 242, 2271), respectively. From the donor perspective, mean cost was $3268 (SD 4704); one-third of donors incurred cost >$3000, and 15% >$8000. The majority of donors (83%) reported inability to perform usual household activities for an average duration of 33 days; 8% reported out-of-pocket costs for assistance with these activities. The economic impact of living kidney donation for some individuals is large. We advocate for programs to reimburse living donors for their legitimate costs.

Previous studies that described the long-term quality of life of living kidney donors were conducted in single centers, and lacked data on a healthy nondonor comparison group. We conducted a retrospective cohort study to compare the quality of life of 203 kidney donors with 104 healthy nondonor controls using validated scales (including the SF36, 15D and feeling thermometer) and author-developed questions. Participants were recruited from nine transplant centers in Canada, Scotland and Australia. Outcomes were assessed a median of 5.5 years after the time of transplantation (lower and upper quartiles of 3.8 and 8.4 years, respectively). 15D scores (scale of 0 to 1) were high and similar between donors and nondonors (mean 0.93 (standard deviation (SD) 0.09) and 0.94 (SD 0.06), p = 0.55), and were not different when results were adjusted for several prognostic characteristics (p = 0.55). On other scales and author-developed questions, groups performed similarly. Donors to recipients who had an adverse outcome (death, graft failure) had similar quality of life scores as those donors where the recipient did well. Our findings are reassuring for the practice of living transplantation. Those who donate a kidney in centers that use routine pretransplant donor evaluation have good long-term quality of life.

OBJECTIVE: Suboptimal levels of 25-hydroxyvitamin D (25OHD) are common in haemodialysis patients (Chronic Kidney disease-5D: CKD-5D) and may be associated with reduced muscle strength and increased falls risk. We tested the hypothesis that 25OHD levels may be independently associated with falls risk in CKD-5D. BACKGROUND: Supplementation with calcium and cholecalciferol reduces hip and other nonvertebral fractures in elderly individuals, and this effect may in part be attributable to reduction in falls frequency. The relationship between 25OHD and falls risk has not been investigated in CKD-5D. DESIGN AND PATIENTS: This is a cross-sectional study of 25 CKD-5D patients with predialysis 25OHD, 1,25-dihydroxyvitamin D (1,25(OH)(2)D) and intact parathyroid hormone (iPTH) measurement. Falls risk was assessed by quadriceps muscle strength, FallsScreen((c)) test (FST), Berg Balance Scale (BBS), timed 'up and go' (TUG) test, Modified Barthel Index (MBI) and Falls Efficacy Scale (FES). RESULTS: Mean age was 69.8 +/- 12.1 years, and median time on dialysis was 3.1 years. Median 25OHD level was 55.3 nmol/l (range 20.8-125.8 nmol/l). Muscle strength was significantly positively correlated with 25OHD (P = 0.024) but not with 1,25(OH)(2)D (P = 0.477) or PTH (P = 0.461). Statistically significant correlation between 25OHD levels and FST (P = 0.028) plus MBI (P = 0.0046) was noted. No significant correlation was detected between falls risk and 1,25(OH)(2)D or PTH. CONCLUSIONS: Suboptimal levels of 25OHD in CKD-5D are associated with reduced quadriceps muscle strength and increased falls risk. 25OHD may be more important than the active renal metabolite 1,25(OH)(2)D for muscle strength with implications for vitamin D choice and goals of supplementation. Further investigation is required to examine effectiveness of calciferol supplementation on the incidence of falls in CKD-5D.

Methods to reimburse living organ donors for the non-medical expenses they incur have been implemented in some jurisdictions and are being considered in others. A global understanding of existing legislation and programs would help decision makers implement and optimize policies and programs. We searched for and collected data from countries that practice living organ donation. We examined legislation and programs that facilitate reimbursement, focusing on policy mechanisms, eligibility criteria, program duration and types of expenses reimbursed. Of 40 countries, reimbursement is expressly legal in 16, unclear in 18, unspecified in 6 and expressly prohibited in 1. Donor reimbursement programs exist in 21 countries; 6 have been enacted in the last 5 years. Lost income is reimbursed in 17 countries, while travel, accommodation, meal and childcare costs are reimbursed in 12 to 19 countries. Ten countries have comprehensive programs, where all major cost categories are reimbursed to some extent. Out-of-country donors are reimbursed in 10 jurisdictions. Reimbursement is conditional on donor income in 7 countries, and recipient income in 2 countries. Many nations have programs that help living donors with their financial costs. These programs differ in operation and scope. Donors in other regions of the world are without support.

BACKGROUND: Discussing long-term medical risks with potential living donors is a vital aspect of informed consent. We considered whether there are global practice variations in the information communicated to potential living kidney donors. METHODS: Transplant professionals participated in a survey to determine which long-term risks are communicated to potential living kidney donors. Self-administered questionnaires were distributed in person and by electronic mail. RESULTS: We surveyed 203 practitioners from 119 cities in 35 different countries. Sixty-three percent of participants were nephrologists, and 27% were surgeons. Risks of hypertension, proteinuria or kidney failure requiring dialysis were frequently discussed (usually over 80% of practitioners discussed each medical condition). However, many practitioners do not believe these risks are increased after donation, with surgeons being less convinced of long-term sequelae compared with nephrologists (P < 0.01). About 30% of practitioners discuss long-term risks of premature cardiovascular disease or death with potential donors. CONCLUSIONS: Transplant professionals vary in the long-term risks they communicate to potential donors. Improving consensus will enhance decision-making, and emphasize best practices which maintain good, long-term donor health.

We reviewed any study where 10 or more healthy adults donated a kidney, and proteinuria, or glomerular filtration rate (GFR) was assessed at least 1 year later. Bibliographic databases were searched until November 2005. 31 primary authors provided additional information. Forty-eight studies from 27 countries followed a total of 5048 donors. An average of 7 years after donation (range 1-25 years), the average 24 h urine protein was 154 mg/day and the average GFR was 86 ml/min. In eight studies which reported GFR in categories, 12% of donors developed a GFR between 30 and 59 ml/min (range 0-28%), and 0.2% a GFR less than 30 ml/min (range 0-2.2%). In controlled studies urinary protein was higher in donors and became more pronounced with time (three studies totaling 59 controls and 129 donors; controls 83 mg/day, donors 147 mg/day, weighted mean difference 66 mg/day, 95% confidence interval (CI) 24-108). An initial decrement in GFR after donation was not accompanied by accelerated losses over that anticipated with normal aging (six studies totaling 189 controls and 239 donors; controls 96 ml/min, donors 84 ml/min, weighted mean difference 10 ml/min, 95% CI 6-15; difference not associated with time after donation (P=0.2)). Kidney donation results in small increases in urinary protein. An initial decrement in GFR is not followed by accelerated losses over a subsequent 15 years. Future studies will provide better estimates, and identify those donors at least risk of long-term morbidity.

Knowledge of the psychosocial benefits and harms faced by living kidney donors is necessary for informed consent and follow-up. We reviewed any English language study where psychosocial function was assessed using questionnaires in 10 or more donors after nephrectomy. We searched MEDLINE, EMBASE, Web of Science, Psych INFO, Sociological Abstracts and CINAHL databases and reviewed reference lists from 1969 through July 2006. Independently, two reviewers abstracted data on study, donor and control group characteristics, psychosocial measurements and their outcomes. Fifty-one studies examined 5139 donors who were assessed an average of 4 years after nephrectomy. The majority experienced no depression (77-95%) or anxiety (86-94%), with questionnaire scores similar to controls. The majority reported no change or an improved relationship with their recipient (86-100%), spouse (82-98%), family members (83-100%) and nonrecipient children (95-100%). Some experienced an increase in self-esteem. A majority (83-93%) expressed no change in their attractiveness. Although many scored high on quality of life measures, some prospective studies described a decrease after donation. A small proportion of donors had adverse psychosocial outcomes. Most kidney donors experience no change or an improvement in their psychosocial health after donation. Harms may be minimized through careful selection and follow-up.

BACKGROUND: Previous studies concerning Alu I/D polymorphism in the ACE gene and ADPKD severity have used the Alu genotypes as a representative of the true biological variable, namely ACE activity. However, wide individual and ethnic differences in the proportion of variance in ACE activity explained by the I/D genotype may have confounded these studies. This investigation examines the association between ADPKD severity and ACE in terms of plasma enzyme activity and I/D genotypes in individuals from three different countries. METHODS: Blood samples were collected from 307 ADPKD patients (116 Australian, 124 Bulgarian and 67 Polish) for determination of ACE activity levels and I/D genotypes. Chronic renal failure (CRF) was present in 117 patients and end-stage renal failure (ESRF) in 68 patients. RESULTS: ACE activity was related to the I/D genotype, showing a dosage effect of the D allele (P=0.006). The proportion of variance due to the Alu polymorphism was 14%. No difference in ACE activity and I/D genotype distribution was found between patients with CRF versus normal renal function (P=0.494; P=0.576) or between those with ESRF versus those without ESRF (P=0.872; P=0.825). No effect of the I/D genotype on age at development and progression to renal failure (CRF; ESRF) was detected in the overall group, and in subgroups based on ethnic origin, linkage status and sex. CONCLUSION: ACE is not likely to play a role as a determinant of ADPKD phenotype severity.
